The AI models we have now will happily run forever if supplied with external power.
That’s quite different from the average human being’s experience! Our biology imposes so many limitations on us that computers don’t have to deal with, and many of these are cognitively non-negligible.
If an AI model ever emerges that can get bored— or tired, or lonely, or annoyed, or anxious, or scared— then I would begin to take seriously the possibility that it experiences existence something like the way we do.
A human will run forever as well if supplied food (external power), a new body (computers degrade) and genetic data protection (hard drives corrupt) :)
While AI models may not be quite there yet, their world seems fairly similar to ours in the important ways of environmental constraints and survival pressures
An AI model needs to evolve its cognition to successfully navigate its training environment for survival.
Shouldn't that satisfy your criteria for suspecting its experiences to be like your own?
